MACHINE FOR MAKING MOUTH-PIECES OR HOLDERS FOR CIGARS, CIGARETTES, 8L0.

SPECIFICATION forming part of Letters Patent No. 400,806, dated April 2, 1889.

Application filed March 28, 1887. Serial No. 232,624. (No model.)

To all whom it may concern:

Be it known that I, ROBERT WV.-THURMAN, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented new and useful Improvements in Machines for Making hfIouth-Iicces or Holders for Cigars, Cigarettes, &c., of which the following is a specification.

Hy invention relates to machines especially adapted for making paper mouth-pieces for ciagarettes and cigars, and adapted also to the manufacture of paper-tubes for other purposes.

The said invention consists in the several novel features of construction and new combinations of parts, hereinafter fully set forth in connection with the drawings forming part of this application, and then specifically pointed out and defined in the claims.

In the annexed drawings, illustrating the invention, Figure 1 is a front elevation of my machine for making paper tubes for cigarette moutlrpieces, and shows a blank in the act of being gripped by the mandrel. Fig. 2 is a perspective view of the working parts of the machine with the supporting framework removed, the operative parts being in the same position as shown in Fig. 1. Fig. 3 is a detail plan of the mandrel, showing a blank with its endinserted beneath the gripping device of the mandrel. Fig. 3 is a cross-section of the same, showing the blank gripped by the mandrel and in the act of being coiled thereon. Fig. 4 is a plan view of the mandrel with mouth-piece coiled thereon. Fig. r is a transverse section of the same. Fig. 5 is a plan view of the mandrel, showing the completed mouth-piece in the act of being thrown off. Fig. 6 is a longitudinal section of the mandrel. Fig. 7 is a view of the completed mouth-piece.

Referring to the above-mentioned figures, the numeral 1 designates any suitable framework, and 2 a mandrel-shaft having bearings in said frame.

as hereinafter explained. On the rear end of the mandrel-shaft 2 is a pinion, 6, through which the mandrel is rotated by means of a large mutilated gear, 7, on the shaft of a power-wheel, S, which can be driven by hand 0: otherwise.

In rolling the paper blank into the desired form for a month-piece the mandrel 3 acts in conjunction with a yielding pressure-roller, 9, and a yielding concaved. pressure-bar, 10, which are respectively arranged in contact with and on opposite sides of the mandrel. The roller 9 is journaled in bearings 11, provided at the upper end-of a spring-standard,

12, which is suitably supported by the machine-frame, and the concaved pressure-bar 10 is formed on or attached to the upper end of a similar spring-standard, 13, having a like support.

The tension of the spring-standards l2 and 13 is such that the roller 9 and pressure-bar 10 are normally in contact with the opposite sid es of the mandrel 3 to hold the paper blank in place while it is being wound into a mouthpiece on the said mandrel but when the mouthpiece is completed, and prior to its removal from the mandrel, the spring-standards 12 and 13 are acted on by levers l4, l5, and 16 in such a manner as to press said standards outward, and thereby remove the roller and pressurebar from contact with the mandrel and attached mouth-piece. These levers 14:, 15, and 16 are pivoted to the machine-frame, as shown, and are acted on by a cam, 17, carried at the forward end of a cam-shaft, 1S,which is driven by gears 19 and 20 from the power-wheel.

Besides the cam l7,the shaft 18 also carries two other cams, 21 and 22, which act at proper intervals on the lower ends of levers 23 and 24, pivoted to the machine-frame. The upper end of the lever 23 is bent over horizontally above the rear end of the. mandrel to press down the rear end of the gripping-finger 5 at the proper time against the pressure of its spring 25, and so raise the forward end of said finger to permit the disengagement of the completed mouth-piece. The movement of the outer end of the gripping-finger to release the mouth-piece while the latter is on the mandrel is but very slight, and is rendered possible from the fact that the depth of the groove in the mandrel is slightly greater than the thickness of the finger. This lever 23 is actuated by the cam 21, as before remarked. The lever 24, actuated by the cam 22, is so formed at its upper end as to bear against the inner side of a spring-pawl, 26, and re lease it from engagement with a notch, 27, in the periphery of a disk, 28, that is fast on the inandrel-shaft, the engagement of said pawl and notched disk being designed to arrest the rotation of the mandrel when the mouth-piece is completed and said mandrel has rotated sul'iichrntly to bring the groove 4 again on top. At the time the pawl 20 and notched disk 28 engage the mutilated gear 7 has rotated sufficiently to become disengaged from the pinion 6 by reason of the plain periphery of said gear being presented toward the pinion. During this interval, however, the cam-shaft 18, actuated by the gears 10 and 20, is free to retate. After the action of the cam 17 011 the lovers 1st, 15, and 16 has caused the springstandards 12 and 13 to remove the roller 9 and pressure-bar 10 from contact with the mandrel 3, and the lever 23, actuated by the cam 21., has disengaged the spring-finger 5 from the completed inouthiiece, the latter will be automatically pushed or removed from the mandrel by means ot an annular ejector, 20, carried by a bell-crank, 30, pivoted in the machine-frame and moving in a guide, 31, arranged as shown. One arm of the bell-crank 30 is connected by a link, 32,with the forward end of a lever, 33, pivoted horizontally near the bottom of the machine-frame. This lever carries a friction-roller, 3t, at its rear end and is actuated by a cam projection, 35, on the power-wheel. After the cam projection 35, actin on the roller 3-1:, has depressed the rear end of the lever and carried the ejector 29 forward on the mandrel, thereby removing the mouth-piece, the ejector 29 will be auto matically retracted by a spring, 36, connected with the forward end of the lever 33, as shown, or otherwise arranged to effect the desired purpose. A slight movement of the lever 23 slightly raises the finger 5 to release the completed mouth-piece and permit it to be removed from the mandrel by the ejector 29 without tearing or mutilating said mouthpiece. After the mouth-piece has been ejected the further movement of the lever 23 raises the finger 5 to the position shown in Fig. 6, to enable one corner of a new blank to be inserted, and when the lever is moved back by a s prir g, 37, provided for that purpose, the spring under the rear end of the finger 5 throws that end of the finger up and causes its forward end to become depressed in the groove 1, and thereby grip the paper blank firmly while it is being coiled on the mandrel.

The paper blank a, Fig. 3, can be fed to the mandrel over a table, 38, (shown in Fig. 1,) though the table is not essential. The forward end of the finger 5 being elevated, as

shown in Figs. 2 and 6, one corner of; the blank will be caught in the groove 4- beneath said finger, and when the lever 23 moves back the spring 25 will cause the finger 5 to grasp the blank and hold it firmly, as shown in Figs. 3 and 3, and with the rotation of the mandrel the blank will be drawn between the mandrel 3 and roller .9, as shown in Fig. 3. \Vith the continued rotation of the mandrel and the cam-shaft 18, the pressure of the levers 1t, 15, and 16 on the spring-standards 12 and 13 is removed and the roller 9 and the pressure bar 10 are allowed to come in close contact with the paper blank as it becomes coiled 011 the mandrel, as shown in F 4 and 4.. It will be seen that the pressure thus exerted by the roller 9 and the concaved bar 10 will cause the paper blank to be coiled smoothly and evenly on the mandrel, and the outer edge of the blank having been previously supplied with an adhesive substance, l), the tube when completed will be firmly united. By the time the paper tube or mouthpiece is completed the lever 23 will have moved forward and released the spring-finger 5 from its engagement with the inner corner of the blank, and the spring-pawl 26 will interlock with the disk 28 and hold the mandrel stationary. The cam projection 35 on the power-wheel now comes in contact with the roller 34 and causes the lever 33 and bellcrank 30 to actuate the annular ejector 29, which moves forward on the mandrel and pushes off the completed tube or mouthpiece c, as shown in Fig. 5.

The form of the mouth-piece c, as shown in Fig. 7, is conical, corresponding with the coufiguration of the mandrel on which it was formed; but it is obvious that with a cylindrical mandrel a paper tube of cylindrical. shape could be produced, if desired.
